The Cidr Report
by Tony Bates 20 Mar '98

20 Mar '98

This is an auto-generated mail on Fri Mar 20 12:00:00 PST 1998 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Nanog Dearborn

Alex, Did you mean Detroit Metro airport or Detroit City Airport? Metro Airport should be your first choice. It is within 10 minutes driving time. City airport is much a smaller airport a bit further away. Still not too far away via I-94. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* | Harold Willison AGIS Network Engineering | * Network Engineer 313-730-5151 * | News Admin. 313-730-1130 | | news(a)agis.net 24 hours a day, 7 days a week | * harold(a)agis.net noc(a)agis.net * | <bold><italic> <underline>http://www.agis.net</underline></italic></bold> |<bold><italic> </italic></bold>\*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*/

> I consider Windows 95 to be the least common denominator, > which has a default IP TTL of 32. Yes, 32. So that implies > that each NSP should decrement no less than 8 TTLs. That's broken. I quote from RFC 1340, dated July 1992: The current recommended default time to live (TTL) for the Internet Protocol (IP) [45,105] is 64. This does not change reality, of course, but it also does not make it less broken. - Håvard

At 19:02 3/18/98 -0500, you wrote: >I'm still shocked that it took 4 days to motify my NIC Handle. Why? I've got email from their brass admitting that their PGP authentication doesn't work; you can register using any name, city, phone number or DNS server you want (whether they exist or not; you don't even have to use numbers in the phone number area); they refuse to administer WhoIs in any manner whatsoever; they can't even afford anyone to answer the phones anywhere but on the payment lines. It shouldn't surprise you that it took 4 days...it should surprise you that you were able to do it at all. Spam: it's not just for breakfast anymore....

New Mailing List... anyone?
by Adam Rothschild 20 Mar '98

20 Mar '98

Everyone: As of late, I've given some serious thought to creating a new mailing list, titled "inet-complaints" or "inet-emergencies" (or some name that's better sounding but indicates the same topic :)... As the name suggests, this would be a place to direct complaints about outages/providers/etc (when ordinary support channels fail)... and hopefully for qualified people to lurk and offer asisstance. I for one could really benefit from such a list, and I'm sure many others could, as well. If anyone has organizational ideas, or would consider hosting the sucker, please let me know. Regards, Adam

Internet Architecture Diagram - Comments Please
by Russ Haynal http://navigators.com . 20 Mar '98

20 Mar '98

Hello all, I have just completed my initial creation of an "Internet Architecture : Meta Diagram" ( http://navigators.com/internet_architecture.html ) My Intention with this page is to answer the Question: "What are the major pieces of the Internet, and who are the major players in each segment?" I have created a "very tall diagram" with 8 sections, covering the connection from a Users's PC -> local Loop -> ISP POP - > Backbones -> online content -> etc. In each section, I hope to mention most of the significant parts of the architecture. I also link to the top couple of vendors in each category, and then link to a more extensive list of vendors. What I am looking for is a sanity check of the diagram, and most importantly, your opinion as to who are the largest 3-4 vendors in each section. I recognize that the diagram is US-centric and contains some leading edge components as well (LMDS, cable modems, etc) I am continuing to refine the page, so any feedback you provide should be incorporated almost immediately. Thanks in advance.
